Roger Mayweather's felony trial on charges that he attacked a female boxer he once trained has been delayed until next year in Las Vegas.

The trial was scheduled to begin Monday but was delayed until Jan. 24, 2011.

It was the second such delay in the trial, which originally was scheduled to begin in August.

The charges stem from an August 2009 incident in which Mayweather, a two-time boxing world champion and now trainer of his nephew, Floyd Mayweather, allegedly assaulted and choked boxer Melissa St. Vil, 26, into near-unconsciousness, according to her claims.

Mayweather was attempting to evict St. Vil from a residence he owns at the time.
